Application filed April 1, 1910. Serial No. 552,818.

a citizen of the United States of America,

residing at Girard. in the county of Crawford and ,State of Kansas, have invented certain new .and useful Improvements in Grain-Shockers. ofwhich the following is a .Tliis invention relates to grain Shockers, the object of the invention being to provide a structure adapted toibe secured to and to travel with a grain binder of the usual constructiomsaid shocker receiving the boundbundles of grain from the binder; retaining said bundles until the desired number of bundles have been collected, and then depositing all ofeaid bundles in the form of a shock upon the ground' Broadly speaking, these objects are attained by a structure comprising a frame in which a table is slid:

ably n'iounted, together with means for conducting the bundles of grain to said table. shock forming arms or fingers for retaining the bundles in an upright position upon said table, means for causing the table to move into the frame and from beneath said bundles at the will of the driver, fingers for supporting the bundles when the table is withdrawn from beneath them, and automatic means for dropping said fingers and opening the shock forming arms when the table reaches its limit of movement toward the front of the machine.

The structure for accomplishing the foregoing objects has been disclosed in the accompanying drawings in which,

Figure 1 is a plan View of a. shock former constructed in accordance with the invention, Fig. Qiis azside elevation thereof, Fig. 3 is a section upon line 33 of Fig. 1, Fig.

Like numerals designate corresponding parts .in all of the figures of the drawings.

' Referring to the drawings, the numeral designates a frame in which a table 6 is frame of a grain binder, and 8, one ofthe rotative shafts of the grain binder. The

shock former is secured to the grain binder frame by bracket arms 9. A longitudinal shaft 10 is supported within the frame 5 and as long as the grain binder is in operation this shaft is driven by means of sprocket. wheels 11 and and a sprocket chain 13, from the shaft 8. A bevel gear 14: upon shaft- 10 meshes with a. bevel gear 15 upon a transverse shaft 1Q. v Loosely mounted upon the shaft 16 are sprocket wheels 17 and 18. Sprocket chains 19 and 20 pass over the sprocket wheels lTand l8 andalso over sprocket wheels 21 and 22, these latter sprocket wheels being fast upon a. trans 'erse shaft 23. The shaft 23 has a bevel gear wheel 24 fast thereon and this bevel gear wheel meshes with bevel gear wheels 25 and of a clutch mechanism hereinafter described and better illustrated in Fig. 6.

The sprocket chains 19 and 20 are secured to the front portion of the table frame as indicated at 27 in Fig. 7, so that as the sprocket chains are actuated, the table is drawn into the frame 5 or projected therefrom, according to the direction of movement of said chains.

The frame of the grain shocker is mounted upon wheels 28' which support the majority of the load of the shocker and relieve the grain binder of the sidedraft that would otherwise be present if the shocker frame were not'mountcd upon independent wheels.

Mounted in longitudinally extending members 5" of the frame are vertical shafts 29 and 30.- These shafts carry bevel gears 31 and-3:2 which mesh with bevel gears 33 and Biwhich are mounted upon shaft 16. The

shafts 29 and carry lowersprocket wheels .and'36. Sprocket'chains 37 and 38 pass around these sprocket wheels and around sprocket wheels 39 and 40 which are 1nourited upon shafts i1 and 42. The shafts 29 and 30also carry upper sprocket Wheels 43 and 44 around which" pass sprocket chains 45' and 46'. These sprocket chains 45- and'46 pass around sprocket wheels 47 and 48 which are mounted upon shafts 49 and 50.

The sprocket chains 37, 38, and 45, 46, are provided with teeth 51 to adapt them to engage the bound bundles of grain-that are discharged from the grain binder and to 5 carry said bundles rearwardly between them and to discharge saidbundles into the shock forming arms hereinafter described. To further assist in the discharge of the bundles of grain into the shock forming arms,

the shafts 29 and 30 carry fingers 52 which rotate bodily with the shafts, and to aid in forcing the bundles into the shock forming arms, a air of vertical shafts 53 and 54 are .provide with offset portions 55 and 56 to i5'permitthepassage of the fingers 52. The shafts and 54 carry shock forming arms 57, 57 57"., and 57. Itwill be seen that the arms 57 are of the smallest radius and that the arms 57 c are of the greatest radius, wherebya shock is formed larger at the bottom than atthe top which is of course desirable since the shock is caused to stand in an upright position upon the ground when discharged, as hereinafter set forth.

links 60 and 61 with a connecting rod 62. This connecting rod is'in turn connected by a link 63 with a centrally disposed crank 64 of a transverse crank shaft 65. A second crank 66 of this crank shaft is connected by a connecting rod 67 to one of the members of a clutch actuating yoke, hereinafter described. The crank shaft 65 carries cranks 6S. Connecting rods 69 are-connected to the cranks68 and to the lower portions of curved levers 70. A yoke 71 (see Figs. 1, 2, 3, and 4) extends entirely across the rear portion of the shocker and serves to support the fingers 72. These fingers are pivotally 40. mounted at their front ends upon a transverse shaft 7 3. j The upper ends of the yoke are inturned and are mounted in bearings 74, and after passing through these bearings they are rigidly connected to the upper portions of the curved levers 70. Cams 7 5 (see Figs. 1 and 4) are carried by the table and serve a purpose which will be set forth in the operation of the machine.

As is best illustrated in Figs. 6, 8, and 9, the clutch mechanism and the controlling elements thereof are arranged asfollows: It is to be understood thdd the gear wheels 25 and 26 are loosely mounted upon the shaft- 10 and that the gear wheel 24 is fast upon the shaft 23. A collar 76 is slidably mounted upon the shaft 10 between the gears '25 and 26. and this collar is adapted when moved longitudinally upon the shaft, to throw the toothed washers 77 or 78 into envgagement with the teeth 79 or 80 of'the gears 25 or 26. It is to be noted that the washers 77 and 78 are splined upon the shaft 10 by means of keys 81 and 82. The

collar; 76 is engaged" by. a forked lever 83 fiemhe rear epdof this le-Verispivoted at 84 Crank arms 58 and 59 are connected lby to ayoke 85 and both the yoke and the forked lever are pivoted to a portion of the frame 5-"(see' Fig. 9). -One end of 'a spring 86 is connected to a bolt 87 which passes through the end of the" yoke 85, and has a nut 88 threaded thereon, whereby the ten-- sion of the spring may be adjusted, and the other end of the spring is connected to the forked lever 83. Projecting from the underside of the forked lever 83, is a pin 89 (see Figs. 8 and 9), and this pin is adapted to be engaged by a latch lever 90, said latch lever being pivoted at 91 to the underside of a portion of the frame 5. A spring 92 is connectedto the lever and to the (frame 5, and normally tends to draw the latch lever lnto engagement with the pin 89. 'A rod or cable 93 is connected to. the outer end of the lever 90 and leads to a pointadjacent the drivers seat (not shown), of the grain binder..

The operation of the device is as follows: During the timethat the shock is being formed, thepin 89 is engaged by the latch lever 90, and the clutch is held in its neutral position. That is, neither of the washers 7 7 78, is in engagement with the teeth 79, 80 of the gear wheels 25, 26. During the passage of the grain binder over the field. the sprocket chains. 37,, 38, and 45,- 46, receive the bound bundles from the grain binder, and the teeth of these sprocket chains, en-

. gaging the bundles, carry them rearwardly to a point adj acent the entrance to the shock forming arms. The fingers .52 swin ing around in the direction of the arrow aig. 1), forces the bundles into the embrace of the shock forming arms. This continues until the desired number of bundles have been collected by the; shock forming arms,-

preferably from six to fifteen bundles, whereupon the rod or ,cable 93 is actuated by the -driver of the grain binder. This withdraws the latch 90 against the tension of the spring 92 from its engagement with the pin 89 and permits the spring 86 to act to throw the toothed washer 78 into engagement with the teeth 80 .of gear 26. The gear 26 will now rotate with -the shaft 10 and actuate the gear 24:. shaft 23. and sprocket chains 19 and 20, to draw the table into the frame 5 and from beneath the shock. When the table travels from beneath the shock, the shock is left standing upon the fingers 72. \Vhen the table reaches its forward limit of movement, the cams 7 5 engage beneath the outer ends of the cranks 68 (which are up to this time occupying a past center position), thereby throwing said cranks upwardly and forwardly. This upward and forward movement of the cranks, through the-medium of the connecting rods 69, throws the lower ends of the curved levers 70 forwardly and upwardly, and consequently throws the yoke .71 forwardly and downwardly, thereby per:

mitting the fingers 72 to drop. Themovement of the crank shaft 65, when the cams 7 engage the cranks 68, results in throwing the crank 64 downwardly and rearwardly, whereupon through the connections described, the; crank arms 58and 59 will be actu'ated, (see Fig. '.5) and the shafts 53 and 54 will be turned upon. their axes to swing 7 will withdraw from beneath the shock, leaving the shock standing upon the ground in' an upright position. The actuation of the crankshaft 65, as hereinbeforeset forth, not only accomplishes the foregoing results, but

fthrouglrthe medium of the'link 67, the yoke 85 is thrown forwardly in Fig. l, bringing the spring 86 (se'eFig. 6)-'to the opposite side of the pivot point 84:, and throwing the forked lever 85 toward the left in Fig. 6.

This results inbringing the washer 77 into engagement with the teeth 7 9 of the gear 25, and reverses the movement of the table and returns the table to its projected position When the table nearly reaches its outwardthe connecting rods 69 and throw the crank.

shaft back to its original position, and this brings the cranks 68 to their past center position (see Fig. 4:). It is apparent that when the crank shaft 65 is returned. to its original position, the shock forming arms will be closed through the connections described. Upon the return of the crank shaft 65 to its original position, the yoke 85 will also be thrown back to its original position, and this would tend to throw the forked lever '83 into such position as to bring the washer 78 immediately into engagement with the teeth 80 of gear 26; but at this time, the spring 92 interposes the latch 90 in the path of the pin 89 of the forked lever, and the forked lever is prevented from moving far enough for the teeth of the washer 78 toengage with the teeth 80, and the clutch remains in its neutral position, during the time that a new shock is being formed preparatory to repeating the above described operation.

" ing the bundle to an upright position by the Byreferring to Fig. 3, it will be seen that the gear wheels 35 and 36 are larger than the gear wheels 43 and Therefore the lower toothed sprocket chains 37, 38 will travel faster than the upper toothed sprocket chains 45 and 46. This will result'in bringtime that it passes from between said chains. These sprocket are close enough 'to each otherto frictionally hold the bundles between them, and to prevent said bundles its from dropping through. It will be noted that the upper sprocket chains dolnot extend as far. forwardas the lower sprocket chains. This permits the bundle, when delivered from'the binder, to fall upon and partially between the lower sprocket chains, and to be carried rearwardly thereby untilIthe upper'portions of the bundles are engaged by the upper sprocket chains. As has been before stated, the fact that the lower sprocket chains travel faster than the upper sprocket chains will thenserve to cause the bundles to a su e a vertical position by the time they are discharged into the shock forming arms.

From the foregoing description, it will be seen that simple and eiiicient-n'ieans are herein provided for accomplishing the objects of the invention, but while the. elements shown and described are well adapted to serve the purposes for which they are intended, it is to beunderstood thatthe invention is not limited to the precise constructionset forth,

but includes within its purview such changes as may be made within the scope of the appended claims,
